Description

Energy-saving low-cost paint diluent

Technical Field

The invention relates to the technical field of chemical production, in particular to an energy-saving and low-cost paint thinner.

Background

When people buy paint coatings, the paint coatings are generally matched with a diluent, the diluent is a liquid substance which is added with good miscibility with resin and is used for reducing the viscosity of the resin and improving the processing performance, and the diluent comprises a reactive diluent and a non-reactive diluent. The thermosetting resin in paint coating needs to be added with thinner to reduce its viscosity for further processing, and these thinner are all organic solvents which are cheaper than resin in practice, so as to reduce the processing cost, however, in the prior art, because the configuration of the thinner is not reasonable, the thinner in the production cannot achieve the required dilution effect, especially for thick paint, and brings loss to manufacturers and consumers.

Disclosure of Invention

In order to solve the technical problems, the invention provides the paint thinner with energy saving and low cost, the preparation method has reasonable configuration, and the prepared paint thinner can meet the dilution requirement and reduce the loss of enterprises and consumers.

The purpose of the invention is realized by the following technical scheme: an energy efficient, low cost paint thinner comprising:

(1) the components are as follows: titanium dioxide: 55-60 parts; linseed oil: 28-35 parts; preservative: 3-8 parts; manganese naphthenate: 1-4 parts; ethylene dichloride: 0.5-3 parts;

(2) adding titanium dioxide, linseed oil and a preservative into an oxidation kettle according to corresponding weight part ratios, uniformly stirring, heating to 85 ℃, blowing air into oil through an air pipe to oxidize the oil and automatically heating to 105-plus 110 ℃, continuously blowing air for oxidation at the temperature until the relative density is measured to reach 0.929-0.930, then installing corresponding weight part ratios, adding dichloroethane and manganese naphthenate, uniformly stirring, and continuously blowing for 35min to obtain the finished product of the oil paint thinner.

The invention relates to an energy-saving and low-cost paint thinner, which comprises the following components in parts by weight: titanium dioxide: 55-60 parts; linseed oil: 28-35 parts; preservative: 3-8 parts; manganese naphthenate: 1-4 parts; ethylene dichloride: 0.5-3 parts; titanium dioxide, linseed oil and a preservative are added into an oxidation kettle according to corresponding weight part ratios, the mixture is stirred uniformly, the mixture is heated to 85 ℃, air is blown into oil through an air pipe, the oil is oxidized and is heated to 105-.

Detailed Description

Example 1
